your local ford dealer should have em, maybe a little pricey, but they might pop up on ebay every now and then also
Another place you might want to try is a shop that sells/installs wheels, they replace factory wheels all the time and you might get lucky and buy the caps off of a set of wheels they have taken off and replaced
